write

A command for implementing a new feature or correcting a defect in a codebase. It selects relevant development practices based on the work involved.

In plain words
What is it for?
It helps build features, fix bugs, update APIs or schemas, change existing code, apply design patterns, handle user input or authentication, and add tests for changed behavior.
Why use it?
It helps ensure that implementation work considers architecture, business logic, refactoring, testing, database changes, security, and other applicable concerns.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

write scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Skills Rubric

To select skills for implementing the feature, consider the following rubric:

Skill When to use
coding:architecture Following a structure recorded in docs/architecture.md, or the memo's forces call for a structural decision (layers, modules, contexts). Defaults to no extra structure when forces are quiet.
coding:domain-modeling The feature is related to business logic or domain entities.
coding:principles Fully new feature no existing code, following principles is essential.
coding:design-patterns The feature needs changes multiple components that can benefit from design patterns.
coding:refactoring Need to change existing code to accommodate the new feature.
coding:testing Each new feature or behavior change requires apply testing.
coding:schema The feature involves database changes, API contracts, or data serialization.
coding:security The feature handles user input, auth, secrets, or crosses trust boundaries.

The language-specific skills not listed, check all available skills before deciding skills to use.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

write is a command published in the GitHub repository elct9620/ai-coding-skills (5 stars, last pushed 7d ago), licensed Apache-2.0. It adds 16 tokens to every session and 2,642 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
